Descriptions
In Libav through 11.11 and 12.x through 12.1, the smacker_decode_tree function in libavcodec/smacker.c does not properly restrict tree recursion, which allows remote attackers to cause a denial of service (bitstream.c:build_table() out-of-bounds read and application crash) via a crafted Smacker stream.
En Libav hasta la versión 11.11 y las versiones 12.x hasta la 12.1, la función smacker_decode_tree en libavcodec/smacker.c no restringe correctamente la recursión de árbol, lo que permite que atacantes remotos provoquen una denegación de servicio (lectura fuera de límites de bitstream.c:build_table() y cierre inesperado de la aplicación) mediante una transmisión Smacker manipulada.
